Title: Non:magnetic swarf separator - uses linear motor producing irregular field to vibrate non:metallic conveying trough
Inventor: LUDA GERD ING GRAD
IPC: B03C1/253
Filed: 1976-10-02
Abstract: The separator to remove non ferrous metal particles (e.g swarf) from oil or other fluids by passing the mixture through a magnetic field, uses a special linear motor to produce a variable irregular magnetic field to bring about a vibratory action. A non metallic trough is used to convey the mixture through the field. The windings of the primary part of the linear motor are subjected to vibration due to a non symmetrical construction. This non symmetrical magnetic field may result from dissimilar windings per groove, non symmetrical poles, different widths of the zones of individual strands of the multi phase windings, variable or non variable damping or short circuit windings, or supplying the individual strands with unequal currents with additional single phase windings.
Patent DE-2652097-A1 (DE)
Title: Wall mounted paper roll dispenser - has housing insertion opening with device preventing subsequent re-extraction
Inventor: THEUNISSEN EOS LEE
IPC: A47K10/38
Filed: 1976-11-16
Abstract: The housing (12) has an insertion opening (15), at which there is a one-way device preventing the roll being extracted through it again (16). There is also a dispensing opening (24) in the housing for the paper from the roll and this can be big enough to allow removal of the core of an empty roll through it. The one-way device can be a spring tongue fixed to the inside of the housing, or alternatively a gravity-operated piece, normally extending into the path of the roll when inserted. The insertion opening can also be of oval section, so that the roll has to be squeezed out of its normal shape for insertion.

Title: Failure indicator for vehicle lights - with delay circuit for testing indicator lamp when switched on
Inventor: SIMON ERNST-ULRICH ING GRAD
IPC: G09G3/04
Filed: 1977-05-20
Abstract: The vehicle lights are grouped in pairs (1, 2) with each pair linked to a failure indicator circuit which illuminates a warning lamp (8) on the dashboard when one of the pair fails. The warning is activated by the current imbalance between the two lamps when one fails. A secondary monitor circuit (10) is fitted to operate the warning indicator every time the ignition is switched on. The driver has a clear indication that the warning indicator bulb is operating every time the ignition is switched on. A simple time delay circuit cancels the warning light after a set time interval.

Title: Unbalanced vibrator for vibrating screens etc. - has one mass on driven shaft and movable second mass guided on swivel bearing
Inventor: THOME LUDWIG DIPL ING DR
IPC: B06B1/16
Filed: 1977-07-27
Abstract: The unbalanced vibrator has two unbalanced masses (13, 14) the first mass being connected to a driven shaft (11) whilst the second is mounted to swivel opposite the first by means of a swivel bearing (19, 22) mounted eccentric to the axis of the driven shaft, with its own axis lying on the side of the shaft axis remote from the centre of gravity S1 of the first mass. The centre of gravity S2 of the second mass (14) lies in the rest position outside of the plane passing through the centre of gravity of the first mass and through the axis of the driven shaft (11). This vibrator has a negative characteristic line when plotting the resulting radius of the centre of gravity above the speed of rotation. The swivel bearing is constructed in a maintenance-free manner.

Title: Antitheft vehicle identification number tape - has engine and chassis numbers permanently applied to rear windscreen and number plate
Inventor: MATZ HELMUT
IPC: B60R13/10
Filed: 1977-08-05
Abstract: The anti-theft identification for the vehicle includes the engine and/or chassis numbers on the licence plate as well as the embossed official stamp. The engine/chassis number is also applied to a special tape and fitted to the rear windscreen. The tape cannot be removed without damaging the number on the tape. This can be achieved with pressure sensitive layers in the tape sandwich, which allow only one fitting. Any attempt to lift the tape bonds it and permanently distorts the information.

Title: Internally driven radial piston pump - has groove in central bore of casing to ensure uniform filling of working chambers on each suction stoke
Inventor: RIEBER ROLAND ING GRAD
IPC: F04B1/04
Filed: 1977-10-13
Abstract: The pump casing (1) has radial cylinders (7) in each of which a hollow piston (6) reciprocates. Each piston is pressed against an eccentric (3) on the drive shaft (2) by a spring (12). The rotation of the eccentric causes the reciprocation. Each piston has holes (13) which enter the crescent shaped space (4) between the casing and the eccentric on the suction stroke and through which the liquid being pumped enters. There is a groove (14) round the circumference of the central bore in the casing. This ensures that on the suction stroke all the holes (13) in the piston are uncovered equally regardless of the rotation of the piston about its own axis.

Title: Prosthesis made of materials to take operational stresses - plus appropriate frictional partner materials and suitable binder
Inventor: ENGELBRECHT ECKHARDT DR MED
IPC: A61F2/36
Filed: 1978-02-11
Abstract: An endoprosthesis replacing a bone or bone part in a living body is made up of a combination of >=2 components, one of which transmits loads and one is a binder. The former itself may consist of two materials. The load-transmitting component of a prosthesis can be a fibrous material e.g. carbon fibre, the binder a material which bonds these fibres together e.g. epoxy resin. Carbon fibres are tolerated by the body, epoxy resins also if all valency bonds are saturated. For joint areas where abrasion occurs e.g. high m.w. polythene and e.g. aluminium oxide ceramic can work together satisfactorily. Minimal movement between bone and prosthesis, optimal loading on bone, minimal degradation changes in bone, combination material is chosen to suit the application.

Title: Apertured diaphragm as viewing aid - has fixed or variable aperture and uses clear or tinted light transmitting material for various light conditions
Inventor: SCHADER HANS DR
IPC: G02C7/16
Filed: 1978-06-16
Abstract: The apertured shutter used as a viewing aid is employed together with a tinted or clear spectacle glass. The shutter is coloured to correspond to the spectacle lenses. The contrast between the aperture and the light-transmitting material is sufficient to achieve the desired sharpness of unison for the eye. The physiological facility for adaptation of the human eye to various light conditions is realised by this arrangement.

Title: Detector measuring torque acting on body - uses laser-illuminated photoelectric detector pairs containing vertically-stacked sensor cells
Inventor: BOHLKEN ROLF
IPC: G01L1/00
Filed: 1978-09-11
Abstract: The detector is for tensional forces acting as a body. Photoelectric detectors are located in pairs (2a, 2b;2c2d) equidistant from the tensional axis (4) of the body. Each detector has vertically stacked discrete sensor cells. A laser source positioned near the tensional axis illuminates the detectors. The detector outputs are compared to form a signal equal to zero when no tension exists. Under tension the laser illuminates sensors at different heights on the detectors giving a difference signal proportioned to the tension.

Title: Electric shunt type filter - increases selection range by using surface oscillator in parallel branch so that it has high capacitance w.r.t. series oscillator
Inventor: HECK WOLFGANG ING GRAD
IPC: H03H9/58
Filed: 1978-11-10
Abstract: The electric shunt type filter has ceramic resonators in the series and parallel branches. To increase the selection range of the resonances in the series branch (1) is series oscillator, the resonances of the parallel branch (2) are derived from a surface oscillator. A voltage generator (3) has a generator resistor (31). The static capacity (11) is created from the electrodes of the resonator (1), while the static capacity (21) is created by the electrodes of the resonator (2). A wide difference between these static capacities (11, 21) is formed to offer a wide selection of amplitudes. A capacity ratio of 1:20 to 1:40 is achieved offering an amplitude selection of more than 30 dB per filter stage. Smaller wiring resistors can be used, e.g. 1.5kOhm for 455kHz.
